Problems solved by technology

[0003] Please refer to the attached figure 1 , in the prior art, since the thickness of the polarizing plate 20 is very thin, when attaching it to the display device panel 10, it is easy to mistakenly stick it into two pieces or even multiple pieces, and this kind of wrong sticking will also be difficult in the later inspection. It is difficult to distinguish, and it is easy to cause missed inspections and cause defective products with two or more polarizers to flow to the client

Embodiment Construction

[0013] Please see attached figure 2 and attached image 3 , the polarizer 20 attached to the display panel 10 at least includes: a polarizer 21 , and a protective film 22 attached to the outer surface of the polarizer. The color of the edge region 23 of the protective film is set to be a color different from that of the polarizer 21 , preferably green which is easy to distinguish from the color of the polarizer 21 .

[0014] After the polarizer 20 is attached to the display device panel 10, the protective film 22 and the polarizer 21 in the polarizer 20 can be easily distinguished by color when viewed from the side of the display device to which the polarizer 20 has been attached. The number of times the film 22 appears can determine whether more than one polarizer is attached to the panel of the display device.

[0015] as attached Figure 4 As shown, when two polarizers 20 are mistakenly attached to the display panel 10, due to the color difference between the protective...

Abstract

The present invention discloses an optical polarization plate and a method for viewing the adhibiting number. The optical polarization plate of the invention at least comprises a polarizing piece and a protective film which is adhibited at the external surface of the polarizing piece. The color of the marginal area of the protective film is arranged to different from the color of the polarizing piece. When the optical polarization plate is adhibited on the panel of the display device and viewed from the display device adhibited with the optical polarization plate, the color of protective film of the optical polarization plate and the color of the polarizing piece can be easily discriminated. The adhibiting number can be determined according to the number of appearing of the protective film.

Description

technical field [0001] The invention discloses a polarizing plate, in particular a polarizing plate used for a display device panel (panel) and a method for inspecting its attached quantity. Background technique [0002] A polarizing plate is a light plate that only allows light in a certain direction to pass through, and is commonly used in various displays. A polarizer is generally composed of a polarizer with a polarizing effect and a protective film attached to the surface of the polarizer to ensure its durability and mechanical strength. [0003] Please refer to the attached figure 1 , in the prior art, since the thickness of the polarizing plate 20 is very thin, it is easy to mistakenly stick it into two pieces or even multiple pieces when sticking it on the display device panel 10, and this kind of wrong sticking will also be difficult in the later inspection. It is difficult to distinguish, and it is easy to cause missed inspections and cause defective products wit...
